摘要
Abstract
The article makes a summary on verification of feasibility study of model LJ20-1A propeller type current meter under random sampling. The dry test equipment is used for the calibration as an auxiliary tool of the calibration tank. The calibration is done by north china inspection and testing center of hydrometric instrument, helical angel of propeller (A) and bearing friction moment (M) are given, and scientific sampling is made according to A. The verification shows that the meters are of high precision, linear equations for middle-high and low velocities are standard, and it is convenient for production and use.关键词
